Apparatus for catching coke oven spillage

Abstract

An apparatus for catching coke oven spillage, generally comprised of a hopper movable along the bench floor located on the pusher side of a coke oven battery. The apparatus is positionable along the bench floor adjacent to any one of the ovens which comprise a coke oven battery such that coke released from the oven on the pusher side during the removal of the coke oven door and return stroke of a pusher ram is captured in the hopper. The apparatus is capable of depositing captured coke back into the particular coke oven.

I claim: 
     
       1. An apparatus, for catching and collecting discharged coke from a coke oven as a consequence of oven door removal on the pusher side and coke oven pullback, located on the pusher side of a coke oven battery, comprising: (a) a platform extending the length of said coke oven battery;   (b) a hopper adapted to fit within said coke oven;   (c) support means for supporting said hopper, said support means being movable along said platform;   (d) elevating means for elevating and horizontally projecting said hopper aloft from said support means and into said coke oven, said elevating means being able to move said hopper horizontally on said support means such that said hopper is adjacent to and below said coke oven to receive any of said coke removed from said oven as a result of coke oven pullback prior to the introduction of said hopper into said oven;   (e) means for tilting said hopper when said hopper is in an elevated position and within said oven; and   (f) positioning means for positioning and repositioning said hopper, and support means along said platform adjacent to any of a predetermined one of said coke oven of said coke oven battery.   
     
     
       2. An apparatus as claimed in claim 1, wherein said elevating means comprises: (a) a plurality of lift tracks fixably mounted to said support means such that said hopper is there-in between, said tracks having a guide wheel surface, said lift track extending horizontally across said support means towards said oven and gradually arching to a vertical extension;   (b) chain fixably mounted to at least one of said tracks horizontally displaced from said guide wheel surface and extending the length of said track;   (c) an axle member rotatably mounted to said hopper;   (d) drive means to rotate said axle;   (e) a plurality of guide wheels rigidly mounted to said axle member and resting on each of said guide wheel surfaces; and   (f) a sprocket fixably mounted to said axle member and cooperatively engaging said chain; whereby rotation of said axle rotates said sprocket which coacts with said chain to propel said hopper along said lift track.     
     
     
       3. An apparatus as claimed in claim 1, wherein said tilt means comprises: (a) a plurality of screw drive motors rotatably mounted to the side of each of said lift tracks, each of said screw drive motors having elongated shaft; and   (b) a member rotatably mounted to said hopper such that said member can rotate parallel to said hopper, said member coactively engaging said elongated shaft such that rotation of said shaft will displace said member along said shaft; whereby rotation of said shaft coacts with said member to effect the trajectory of said hopper.     
     
     
       4. An apparatus as claimed in claim 1, wherein said positioning means comprises: (a) a plurality of axles rotatably mounted to said support means;   (b) a plurality of wheels fixably mounted to said axle;   (c) a plurality of rails fixably mounted to said platform, said wheels aligned to ride along said rails; and   (d) second drive means for rotating at least one of said axles.   
     
     
       5. An apparatus, for catching coke discharged from a coke oven due to oven door removal on the pusher side and coke oven pullback, located on a bench floor of a battery of coke ovens on the pusher side, which comprises: (a) a hopper adapted to enter into a coke oven;   (b) means for supporting said hopper;   (c) a plurality of lift tracks fixably mounted to said support means, at least one of said tracks positioned to either side of said hopper, said lift tracks extending horizontally across said support means towards said oven, gradually arching to a vertical extension, said tracks having a guide wheel surface;   (d) a chain fixably mounted to the upper surface of said track horizontally removed from the guide wheel surface extending the length of the upper surface;   (e) an axle member rotatably mounted to said hopper;   (f) drive means to rotate said axle;   (g) a guide wheel rigidly mounted to said axle member resting on said guide wheel surface;   (h) a sprocket fixably mounted to said axle member and cooperatively engaging said chain, whereby activation of said drive means rotates said axle, thereby rotating said sprocket which coacts with said chain to propel said hopper along said lift track;   (i) a plurality of screw drive motors, at least one rotatably mounted on the side of each of said lift tracks, said screw drive motors having an elongated shaft which is threaded;   (j) a plurality of members, at least one rotatably mounted to each side of said hopper, each of said members having a toothed hole therein adapted to cooperatively engage said shaft, whereby activation of said screw drive motors rotate said shaft within said member to effect the trajectory of said hopper;   (k) a plurality of axles rotatably annd supportably mounted to said support means;   (l) a plurality of wheels fixably mounted to said axle;   (m) a plurality of rails fixably mounted to said platform, said wheels aligned to ride along said rail; and   (n) drive means for rotating at least one of said axles.
